Not my best replica, started off as a test bed for undercarriage, then flaps and general centre of lift / aero balance. It ended up too tall to be an accurate Huckbein but could easily have been a later development (is used the additional space for fuel so you never know the real one might have also been altered, imagination required.) Vtol down for flaps, landing gear and doors all on the usual button, flies really nice and is very manoeverable at high speed (usual thing where you need the extra control surface movement at slow speed which equates to silliness at high speed, if you use a joystick its easily manageable, if you dont its still flyable but a bit more twitchy)
